redundant keigo; double honorific
A linguistic term for an improper combination of honorific forms, such as using the passive honorific ～られる together with a verb that is already honorific (e.g., おっしゃられる instead of おっしゃる). Often cited as a common mistake in business Japanese.

"Ossharareru" is a typical example of redundant keigo.
In business writing, one must be careful about double honorifics.
